j Attach the IW Evaporator Assembly to the bus
structure using the appropriate hardware. See
Figure 2-45 and Figure 2-46.
k Remove plugs or tape from the hose ends and
attach the appropriate fittings to the hose assemblies.
Refer to Section 4, Hose Routing Procedures.
NOTE
Do not remove plugs from the expansion valve
or hose ends until you are ready to attach fit-
tings to the hose and then to the evaporator as-
sembly.
l Carefully connect suction and liquid refrigerant lines
to block valve. Refer to Section 4, Hose Routing
Procedures.
CAUTION
Because of the limited access to the block
valve, start the fittings by hand (finger tight-
ening) making sure that there is no cross-
threading before tightening. When tighten-
ing the fittings, make sure that the Block
Valve does not move.
m Connect the evaporator harness to the In-Wall
evaporator. Make sure all wires are secure in the
butt-connectors. Refer to Section 5, Electrical.
n Securely ground the evaporator using the green
wire in the harness to the structure rail. Normally this
ground wire would be secured to a chassis rail under the
bus.
o Connect the drain lines to the In-Wall evaporator.
Make sure the drain lines run down hill. Always clamp
the drain hose to the evaporator assembly. See
Figure 2-45.
NOTE
Drain lines must always drain to both sides of
the vehicle.
